Abstract

A user equipment (UE) is configured to perform uplink power control. The UE determines, based on a look-ahead window, that a first uplink transmission is scheduled to overlap in time with a second uplink transmission; determines a first transmission power for the first uplink transmission; determines a second transmission power for the second uplink transmission based on the first transmission power for the first uplink transmission; and performs the first uplink transmission and the second uplink transmission.

Description

Background Art

[0001] A user equipment (UE) may be equipped with a dual connectivity (DC) function. Generally speaking, there are two types of power sharing schemes that can be implemented by the UE for DC. One type of power sharing scheme may be referred to as semi-static power sharing (SPS). For SPS, the UE transmit power may be shared semi-statically between the master cell group (MCG) and the secondary cell group (SCG). Another type of power sharing scheme may be referred to as dynamic power sharing (DPS). For DPS, the UE may dynamically adjust the UE transmit power in one cell group based on the transmission activity in another cell group. Summary of the Invention

[0002] Some exemplary embodiments relate to a processor of a user equipment (UE) configured to perform operations. These operations include: determining, based on a look-ahead window, that a first uplink transmission is scheduled to overlap in time with a second uplink transmission; determining a first transmission power for the first uplink transmission; determining a second transmission power for the second uplink transmission based on the first transmission power for the first uplink transmission; and performing the first uplink transmission and the second uplink transmission.

[0004] A further exemplary embodiment relates to a processor of a user equipment (UE) configured to perform operations. These operations include: receiving an indication scheduling a first transmission on at least one symbol of a first time slot on a first component carrier (CC) of a secondary cell group (SCG); determining that the first transmission is scheduled to overlap in time with a second transmission on a second CC of the SCG; determining whether at least one symbol of the first transmission or the second transmission is scheduled to overlap in time with at least one symbol on a CC of a master cell group (MCG) indicated as uplink or flexible; when at least one symbol of the first transmission or the second transmission on the SCG is scheduled to overlap in time with at least one CC of the MCG indicated as "uplink" or "flexible", determining a first transmission power for the first transmission and a second transmission power for the second transmission based on a maximum transmission power parameter configured for the SCG; and performing the transmission of the at least one symbol of the first time slot.

[0013] The exemplary embodiments can be further understood with reference to the following description and the related drawings, in which like elements are denoted by the same reference numerals. The exemplary embodiments relate to uplink power control for dual connectivity (DC).

[0014] The exemplary embodiments are described with reference to a user equipment (UE). However, the use of the UE is for illustrative purposes only. The exemplary embodiments can be utilized with any electronic component that can establish a connection with a network and is configured with hardware, software, and / or firmware for exchanging information and data with the network. Thus, the UE described herein is used to represent any electronic component.

[0015] The exemplary embodiments are also described with reference to a next-generation radio access network (NG-RAN) that supports DC to multiple nodes each providing 5G new radio (NR) access, such as NR-NR DC. For example, a UE can be connected to a master node (MN) and a secondary node (SN) that are connected to each other via a non-ideal backhaul. However, any reference to a particular type of RAN, a particular type of DC, or a particular type of node (e.g., cell, base station, etc.) is for illustrative purposes only. The exemplary embodiments can be applicable to any suitable DC configuration.

[0016] The exemplary embodiments relate to uplink power control. Generally speaking, there are two types of power sharing schemes for uplink power control in the context of NR-NR DC - a semi-static power sharing (SPS) scheme and a dynamic power sharing (DPS) scheme. For SPS operation, the UE transmit power can be shared semi-statically between a master cell group (MCG) and a secondary cell group (SCG). For DPS operation, the UE can dynamically adjust the transmit power for one cell group based on the transmission activity in the other cell group.

[0017] As will be described in more detail below, the exemplary embodiments include various techniques for improving the flexibility and efficiency of SPS and DPS. These exemplary techniques can be used with other currently implemented SPS and DPS techniques, future specific implementations of SPS and DPS techniques, or independently of other SPS and DPS techniques.

[0018] Figure 1FIG. 100 shows an exemplary network arrangement 100 in accordance with various exemplary embodiments. The exemplary network arrangement 100 includes a UE 110. Those skilled in the art will understand that the UE 110 can be any type of electronic component configured to communicate via a network, such as, for example, a mobile phone, a tablet computer, a desktop computer, a smart phone, a phablet, an embedded device, a wearable device, an Internet of Things (IoT) device, etc. It should also be understood that an actual network arrangement may include any number of UEs used by any number of users. Thus, providing an example of a single UE 110 is for illustrative purposes only.

[0019] The UE 110 can be configured to communicate with one or more networks. In the example of network configuration 100, the network with which the UE 110 can communicate wirelessly is the Next Generation Radio Access Network (NG-RAN) 120. However, it should be understood that the UE 110 can also communicate with other types of networks (such as, for example, 5G Cloud RAN, LTE-RAN, traditional cellular networks, WLAN, etc.), and the UE 110 can also communicate with a network via a wired connection. Referring to the exemplary embodiments, the UE 110 can establish a connection with the NG-RAN 120. Thus, the UE 110 can have a 5G NR chipset to communicate with the NG-RAN 120.

[0020] The NG-RAN 120 can be part of a cellular network that can be deployed by a cellular provider (such as, for example, Verizon, AT&T, T-Mobile, etc.). The network 120 can include, for example, nodes, cells, or base stations (Node B, eNodeB, HeNB, eNBS, gNB, gNB Distributed Unit (gNB-DU), gNB Centralized Unit (gNB-CU), gNodeB, macro cell base station, micro cell base station, small cell base station, femto cell base station, etc.) configured to send and receive traffic from UEs equipped with appropriate cellular chipsets.

[0021] For DC, the UE 110 can be connected to the NG-RAN 120 via the master node (MN) 120A and the secondary node (SN) 120B. The MN 120A and the SN 120B can be connected via a non-ideal backhaul (not shown). Those skilled in the art will understand that the MN 120A can be one of the multiple nodes forming the master cell group (MCG), and the SN 120B can be one of the multiple nodes forming the secondary cell group (SCG). It will be further understood that any relevant processes can be performed so that the UE 110 is connected to the NG-RAN 120. For example, as discussed above, the NG-RAN 120 can be associated with a specific cellular provider, where the UE 110 and / or its user have contract and credential information (e.g., stored on the SIM card). Once the presence of the NG-RAN 120 is detected, the UE 110 can transmit the corresponding credential information to be associated with the NG-RAN 120. More specifically, the UE 110 can be associated with a specific node, cell, or base station. Once associated, the NG-RAN can configure a specific node as the MN and then configure the UE 110 with the SN to provide the DC function. However, as described above, the use of the NG-RAN 120 is for illustrative purposes, and any suitable type of RAN can be used.

[0022] In addition to the NG-RAN 120, the network arrangement 100 further includes a cellular core network 130, the Internet 140, an IP multimedia subsystem (IMS) 150, and a network service backbone 160. The cellular core network 130 can be regarded as an interconnected set of components that manage the operations and traffic of the cellular network. It can include the EPC and / or 5GC. The cellular core network 130 also manages the traffic flowing between the cellular network and the Internet 140. The IMS 150 can generally be described as an architecture for delivering multimedia services to the UE 110 using IP protocols. The IMS 150 can communicate with the cellular core network 130 and the Internet 140 to provide multimedia services to the UE 110. The network service backbone 160 communicates directly or indirectly with the Internet 140 and the cellular core network 130. The network service backbone 160 can generally be described as a set of components (e.g., servers, network storage arrangements, etc.) that implement a set of services that can be used to extend the functions for the UE 110 to communicate with various networks.

[0023] Figure 2 An exemplary UE 110 is shown in accordance with various exemplary embodiments. It will be referred to Figure 1The UE 110 is described in terms of a network arrangement 100. The UE 110 can represent any electronic device and can include a processor 205, a memory arrangement 210, a display device 215, an input / output (I / O) device 220, a transceiver 225, and other components 230. The other components 230 can include, for example, an audio input device, an audio output device, a battery providing a limited power source, a data acquisition device, a port for electrically connecting the UE 110 to other electronic devices, a sensor for detecting the condition of the UE 110, and the like.

[0024] The processor 205 can be configured to execute multiple engines of the UE 110. For example, the engines can include an uplink power control engine 235 for DC. The uplink power control engine 235 for DC can perform various operations related to the SPS scheme and the DPS scheme to be used for DC.

[0025] The above engines are merely exemplary as applications (e.g., programs) executed by the processor 205. The functions associated with the engines can also be represented as separate combined components of the UE 110, or can be modular components coupled to the UE 110, e.g., integrated circuits with or without firmware. For example, an integrated circuit can include an input circuit for receiving signals and a processing circuit for processing the signals and other information. The engines can also be embodied as one application or multiple separate applications. Additionally, in some UEs, the functionality described for the processor 205 is shared between two or more processors such as a baseband processor and an application processor. The exemplary embodiments can be implemented in any of these or other configurations of the UE.

[0026] The memory 210 can be a hardware component configured to store data related to the operations performed by the UE 110. The display device 215 can be a hardware component configured to display data to a user, while the I / O device 220 can be a hardware component that enables a user to make inputs. The display device 215 and the I / O device 220 can be separate components or can be integrated together (such as a touch screen). The transceiver 225 can be a hardware component configured to establish a connection with the NG-RAN 120. Thus, the transceiver 225 can operate at various different frequencies or channels (e.g., a set of contiguous frequencies).

[0027] As described above, the exemplary embodiments relate to uplink power control for DC. In DC, the UE 110 may transmit signals to the MCG including at least the MN 120A using one or more component carriers (CCs). Similarly, the UE 110 may transmit signals to the SCG including at least the SN 120B using one or more CCs. The examples provided below will be described with reference to uplink communications transmitted via the physical uplink shared channel (PUSCH). However, the reference to the PUSCH is for illustrative purposes only, and the exemplary embodiments may be applicable to any suitable uplink transmission on any suitable channel.

[0028] In a first aspect, the exemplary embodiments relate to DPS. Various examples of the exemplary DPS techniques will be described in more detail below with reference to Figures 3 to 5 In a second aspect, the exemplary embodiments relate to SPS. Various examples of the exemplary SPS techniques will be described in more detail below with reference to Figures 7 to 8 Various examples of the exemplary SPS techniques.

[0029] Figure 3 A method 300 for implementing look-ahead window-based DPS according to various exemplary embodiments is shown. Method 300 will be described with reference to Figure 2 the UE 110 of Figure 1 and the network arrangement 100 of

[0030] First, consider the following exemplary scenario where the UE 110 is configured with DC and is connected to the MCG and the SCG. The MCG includes at least the MN 120A, and the SCG includes at least the SN 120B. There is at least one CC between the UE 110 and the MCG, and there is at least one CC between the UE 110 and the SCG.

[0031] As will be explained in more detail below, for DPS, the UE 110 may determine the total transmit power on the SCG at the start of the transmission opportunity on the SCG by determining the transmit power of the overlapping transmissions on the MCG. The UE 110 may identify the overlapping transmissions by using a look-ahead window.

[0032] In 305, the UE 110 configures the look-ahead window size. The look-ahead window can be used to identify overlapping transmissions on the MCG and SCG. Throughout this specification, the term "look-ahead window" refers to the duration of each preamble transmission between CCs on the SCG during which the UE 110 monitors the downlink control information (DCI) on the CC of the MCG that schedules a subsequent transmission on the CC of the MCG. The UE 110 can use the DCI received on the CC of the MCG during the look-ahead window to identify overlapping transmissions between the MCG and the SCG, and determine the transmission power of the overlapping transmissions based on any one of the various different rules described in more detail below. Those skilled in the art will understand that once this look-ahead window-based power determination procedure is enabled with the DPS scheme via UE-specific RRC signaling, the UE 110 applies this look-ahead window-based power determination procedure.

[0033] Figure 4 An example of a look-ahead window according to various exemplary embodiments is shown. The example includes a CC 410 corresponding to the MCG through which the UE 110 receives DCI 412 that schedules a PUSCH 414. The example also includes a CC 420 corresponding to the SCG through which the UE 110 receives DCI 422 that schedules a PUSCH 424. The start of the PUSCH 424 can provide a basis for a time offset (T_offset) 430. T offset 430 can provide a basis for determining a look-ahead window 440 for the PUSCH 424.

[0034] The look-ahead window 440 and / or T offset 430 can be configured in any one of a variety of different ways. As indicated above, in this example, the look-ahead window 440 is defined as having a duration of the last symbol that is earlier than the T offset 430 symbols starting from the transmission occasion on the SCG (e.g., PUSCH 424). Other examples of how the look-ahead window 440 and / or T offset 430 can be configured will be provided below after the description of method 300.

[0035] Returning to method 300, at 310, UE 110 receives two or more instances of DCI (e.g., DCI 412, DCI 422), where the two or more instances of DCI are transmitted within the look-ahead window 440. At 315, UE 110 determines that the uplink transmission to the MCG (e.g., PUSCH 414) is scheduled to overlap in time with the uplink transmission to the SCG (e.g., PUSCH 424) based on the value of the time-domain resource allocation (TDRA) in the received DCI 412, 422. At 320, UE 110 determines the transmission power for the uplink transmission to the MCG. UE 110 can determine the transmission power for the uplink transmission to the MCG in any of a variety of different ways. For example, DCI 412 can include various reference signals. UE 110 can determine the transmission power at least in part based on parameters derived from the reference signals. In other designs, the transmission power of PUSCH 414 can be determined based on the information provided by DCI format 412 (e.g., MSC, allocated resource blocks, etc.). Exemplary embodiments are not limited to determining the transmission power for the uplink transmission to the MCG in any particular way and can be applied to determining such uplink transmission power in any suitable way.

[0036] At 325, UE 110 determines the transmission power for the uplink transmission to the SCG at least in part based on the transmission power for the uplink transmission to the MCG. Doing so can ensure that the total transmission power does not exceed the maximum power level of UE 110. Thus, UE 110 can dynamically determine the transmission power to be used for the SCG based on the transmission power to be used for the overlapping transmission on the MCG.

[0037] At 330, UE 110 can perform the transmission to the SCG. For example, UE 110 can transmit on PUSCH 424 using the transmission power determined at 325. Those skilled in the art will understand the operations performed by UE 110 to generate the transmission and output the signal to the SCG via radio using the determined transmission power. Subsequently, method 300 ends.

[0038] As described above, the look-ahead window 440 and / or T offset 430 can be configured in any of a variety of different ways. In some embodiments, T offset 430 can be determined based on the processing time defined for all CCs within the MCG corresponding to the reference subcarrier spacing (SCS) and / or the processing time defined for all CCs within the SCG. This ensures T offsetThe value of 430 can consider two sequential calculations, e.g., i) decoding the DCI for the PUSCH on the MCG scheduling, and ii) determining the transmit power for the PUSCH on the SCG. Since the parameters can vary between synchronous DC operation and asynchronous DC operation, T can be used based on whether synchronous DC operation or asynchronous DC operation is configured. offset different values of 430.

[0039] UE 110 can use any one of various different techniques to determine the reference SCS. The first technique includes selecting the minimum SCS among the CCs within the corresponding cell group (e.g., MCG or SCG). The second technique includes selecting the minimum SCS among the active bandwidth parts (BWPs) of the CCs within the corresponding cell group (e.g., MCG or SCG). The third technique includes using the reference SCS configured by radio resource control (RRC) signaling, and can vary on a per-UE basis. The fourth technique includes using a pre-configured reference SCS. For example, different SCS values can be defined for frequency range 1 (FR1) and FR2.

[0040] In other embodiments, T offset 430 can be based on to determine. Here, represents the maximum UE 110 processing time among any of the following possible values based on the reference SCS for the MCG: T as specified in Technical Specification (TS) 38.213 v.15.0 and (TS) 38.214 v.15.0 proc,2 , T proc,CSI , and Similarly, represents the maximum UE 110 processing time among any of the following possible values based on the reference SCS for the SCG: T as specified in Technical Specification (TS) 38.213 v.15.0 and (TS) 38.214 v.15.0 proc,2 , T proc,CSI , and

[0041] In some embodiments, T offset the value of 430 can be based on the DPS mode. For DPS mode - 1, Here, represents the maximum UE 110 processing time among any of the following possible values based on the reference SCS for the MCG: T as specified in Technical Specification (TS) 38.213 v.15.0 and (TS) 38.214 v.15.0 proc,2 , T proc,CSI , and Similarly, represents the maximum UE 110 processing time among any of the following possible values based on the reference SCS for SCG: T as specified in Technical Specification (TS) 38.213 v.15.0 and (TS) 38.214 v.15.0 proc,2 , T proc,CSI , and For DPS mode - 2, Here, represents the maximum UE 110 processing time among any of the following possible values based on the reference SCS for MCG: T as specified in Technical Specification (TS) 38.213 v.15.0 and (TS) 38.214 v.15.0 proc,2 , T proc,CSI , and Similarly, represents the maximum UE 110 processing time among any of the following possible values based on the reference SCS for SCG: T as specified in Technical Specification (TS) 38.213 v.15.0 and (TS) 38.214 v.15.0 proc,2 , Tproc ,CSI , and The difference between DPS mode - 1 and DPS mode - 2 is that DPS mode - 2 does not consider UE 110 can use UE 110 capability information to indicate its support for DPS mode - 1 or DPS mode - 2.

[0042] In a normal situation, if an aperiodic channel state information (CSI) feedback on the MCG is triggered, a scenario may occur where UE 110 determines the SCG transmit power before the MCG transmit power is determined. Therefore, if the aperiodic CSI feedback is triggered by DCI on the MCG, UE 110 can determine the maximum transmit power on the MCG based on the allocated transmit power of the overlapping SCG transmission. For example, UE 110 can reduce the transmit power on the MCG during any part of the transmission duration in this type of scenario such that the total transmit power of the MCG and SCG in any part does not exceed the maximum transmit power. Therefore, compared to the example provided in method 300, the MCG transmit power can be determined based on the SCG transmit power.

[0043] In some embodiments, a specific value of T offset 430 can be pre - configured. For example, the first value of T offset = 4 milliseconds (ms), and T offsetThe second value = 1.5 ms. The UE 110 may be pre-configured to support the first value or the second value. Using the pre-configured value allows the UE 110 to indicate its capabilities to the network during initial access.

[0044] In other embodiments, the UE 110 may be pre-configured with a first value of T offset 430 and a second value greater than the first value, where the first value is to be used for synchronous DC within the context of NR-NR DC, and the second value is to be used for asynchronous DC within the context of NR-NR DC. The second greater value may be represented by , where represents the first value to be used for synchronous DC, δ is a pre-configured value (e.g., 1 ms or 2 ms), and K is a scaling factor (e.g., 2 or 1.5).

[0045] In some embodiments, the value of T offset 430 may be based on the following equation: Here, represents the maximum UE 110 processing time based on any of the following possible values for the reference SCS used for MCG: T as specified in Technical Specification (TS) 38.213 v.15.0 and (TS) 38.214 v.15.0 proc,2 , T proc,CSI , and There may be two values for Δ, e.g., Δ1 and Δ2. The UE 110 may be pre-configured to use Δ1 or Δ2 based on the UE 110 time processing requirements. During operation, the UE 110 may use 1-bit RRC signaling to indicate whether it supports Δ1 or Δ2. A single Δ or a pair of Δ1 or Δ2 may be determined using Figure 5 Table 500 based on the SCS of MCG and SCG and the UE 110 processing capabilities settings. In Table 500, Case 1 represents the same or smaller SCS or processing time on MCG, and Case 2 represents a greater SCS or processing time on MCG.

[0046] Figure 6 FIG. 600 shows a signaling diagram for inter-node signaling for look-ahead determination according to various exemplary embodiments. The signaling diagram 600 includes a UE 110, a MN 120A, and a SN 120B.

[0047] At 605, the MN 120A sends a secondary node addition request to the secondary node 120B. Those skilled in the art will understand the content and format of the secondary node addition request.

[0048] At 610, SN 120B sends a secondary node addition request confirmation. This message may also include an indication of a set of parameters (such as SCS configuration, processing time configuration, and information related to d 1,1 and d 2,2 ). These parameters may be sent to MN 120A in a multi-radio DC (MR-DC) container. In some embodiments, the SCS configuration may be used for each BWP of each serving cell in the SCG. In other embodiments, the minimum SCS for all BWPs across all configured CCs on the SCG. The processing time configuration may indicate the capabilities 1 or 2 of each CC or at least one CC of the SCG. The value of d 2,2 depends on whether BWP switching is configured to occur on the SCG CC. The maximum value of d 1,1 depends on whether less than 7 physical downlink shared channel (PDSCH) symbols will be applied on the SCG CC.

[0049] At 615, MN 120A sends an RRC reconfiguration message to UE 110. The RRC reconfiguration information may enable UE110 to establish a connection with SN 120B. Various parameters may be relayed to UE 110 in this message. In some embodiments, UE 110 may use the parameters relayed to UE 110 to determine T offset 430.

[0050] As indicated above, UE 110 may be configured to indicate to the network whether UE 110 supports DPS for synchronous DC operation and / or asynchronous DC operation. For example, UE 110 may provide UE capability information via 1-bit RRC signaling, or provide any other suitable type of message indicating whether UE110 supports DPS for asynchronous DC operation and / or synchronous DC operation.

[0051] In a second aspect, an exemplary embodiment relates to implementing an exemplary SPS technique. Figure 7 A method 700 for a semi-static power sharing scheme (SPS) according to various exemplary embodiments is shown.

[0052] At 705, UE 110 receives an indication of the transmission scheduling at least one symbol of a first time slot. For example, UE 110 may receive an indication that at least one symbol of the first time slot of the MCG or SCG is scheduled for uplink or flexible RRC signaling.

[0053] At 710, the UE 110 determines whether the at least one symbol of the first time slot overlaps in time with an ongoing transmission. For example, the UE 110 may determine that the at least one symbol of the first time slot overlaps with at least one symbol of a second time slot of the SCG or MCG. If an overlap is identified, method 700 proceeds to 715.

[0054] At 715, the UE 110 determines the transmission power of the at least one symbol of the first time slot using a maximum transmission power parameter. The maximum transmission power parameter corresponding to each cell group (e.g., P SCG or P MCG ) may be indicated by RRC signaling. Returning to 710, if there is no overlap, method 700 proceeds to 720.

[0055] At 720, the UE 110 determines the transmission power of the at least one symbol of the first time slot without using the maximum transmission parameter. An exemplary scenario of the SPS scheme of method 700 is shown below in Figure 8 .

[0056] Figure 8 Exemplary scenarios related to SPS when there are overlapping time slots in a CC are shown in accordance with various exemplary embodiments. In this example, for CC#0 of the MCG and CC#1 of the SCG, the SCS is 15 kilohertz (kHz). Additionally, for CC#2 of the SCG, the SCS is 30 kHz.

[0057] According to the SPS scheme described above in method 700, the total transmission power of PUSCH#1 and PUSCH#2 is limited by the maximum transmission power parameter P SCG because PUSCH#1 partially overlaps with the uplink symbols on CC#0 of the MCG. Even though there is no overlap between PUSCH#2 on CC2 and the uplink symbols on CC#0, PUSCH#2 may still be limited by the transmission power parameter P SCG . Doing so can avoid a change in transmission power midway through the transmission of PUSCH#1 when the transmission of PUSCH#2 ends.
